CB360 Composite National Rankings #13 (May 12)

Each of the top-10 teams inCB360’s exclusive Compositional National Rankings remains in the same spot from the previous week (click on above link for CNR archive), led by Arizona State making its eighth straight appearance in the CNR #1 position. ASU-Texas-Virginia have been 1-2-3 for each of the past four weeks, with UVa the only team to be 4th or higher in the CNR throughout the 2010 season.

The remainder of the CNR top-10 remains as follows: #4 Florida, #5 Coastal Carolina, #6 Louisville, #7 Arkansas, #8 UCLA, #9 Florida State and #10 Georgia Tech. The four teams rotating into this week’s CNR top-50 update include a surging Southern Mississippi team that is “back from the dead” and has returned to the top-50 for the first time in seven weeks.

COMPOSITE NATIONAL RANKINGS (CNR) CRITERIA: CB360’s 100-point Composite National Rankings formula currently is centered around 15 core ingredients – combining a diverse collection of “experts” (ranging from coaches, various media, computer calculations and projections) – to help provide a preview of teams that could be in the running for the 2010 NCAA Championship field (hypothetically 50 teams, plus 14 others from lower-rated automatic-bid conferences – those teams will be projected in upcoming CNR updates). Later in the season, other factors – such as “last-10-games” records – will be included in the CNR formula, with CollegeBaseball360 soon to begin generating its own projection of the NCAA field (based on the CNR formula).

Here’s the breakdown of the current “15-ingredient” CNR formula (three main areas):

• Five RPI-Type Ratings: Official NCAA RPI … Boyds World ISR and Pseudo-RPI … and Warren Nolan’s RPI and NRPI

• Five NCAA Tournament Field Projections: from Baseball America, Rivals,SEBaseball.com and ESPN.com bracketology

Teams receive points based on their standings in each poll/rating/projection (60 pts for #1, 59 for #2, etc.). For polls involving voting points (coaches and CB) and the RPI ratings, the CNR adjusts to reward teams that have larger margins in the voting/point totals (whereas two teams with nearly the same voting-point total will be closer in the CNR allotment for that poll). Note that strength-of-schedule typically is factored into RPI formulations … thus the actual SOS numbers are not used in the CNR when RPI already are in the mix. For the NCAA field projections, teams are awarded CNR points based on their respective seedings, “last in” and “last out,” etc.

The 15 core factors are averaged, with 40 points then added to each total in order to yield the 100-point benchmark.
